How to delete email after importing csv attachment to sheets

[Peter Chabot]

I found this script that is working correctly except it doesn't pull the data from the most recent email, it only pulls it from the first one.  If someone could help me configure it to delete the email after it pulls the .csv attachment that would be perfect.

Thanks!

function importCSVFromGmail() { 

  //gets first(latest) message with set label

  var threads = GmailApp.getUserLabelByName('South Loop Report').getThreads(0,1);     

  var message = threads[0].getMessages()[0];

  var attachment = message.getAttachments()[0];

  // Is the attachment a CSV file

  attachment.setContentTypeFromExtension();

  if (attachment.getContentType() === "text/csv") {                            

    var ss = SpreadsheetApp.getActive();

    var sh = ss.getSheetByName("Sheet1");

    //parses content of csv to array

    var dataString = attachment.getDataAsString();

    var csvData = CSVToArray(dataString);

    // Remember to clear the content of the sheet before importing new data

    sh.clearContents().clearFormats();                                         

    //pastes array to sheet

    var lastRowValue = sh.getLastRow();

    for (var i = 0; i < csvData.length; i++) {

       sh.getRange(i+lastRowValue+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));

    } 

  }

  //marks the Gmail message as read and unstars it (Filter sets a star)

  message.markRead();                                                          

  message.unstar();                                                            

}

//The code formats the code so it can be entered into the Google Script

function CSVToArray( strData, strDelimiter ){ 

  // Check to see if the delimiter is defined. If not,

  // then default to comma.

  strDelimiter = (strDelimiter || ",");

  // Create a regular expression to parse the CSV values.

  var objPattern = new RegExp(

    (

      // Delimiters.

      "(\\" + strDelimiter + "|\\r?\\n|\\r|^)" +

      // Quoted fields.

      "(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +

      // Standard fields.

      "([^\"\\" + strDelimiter + "\\r\\n]*))"

    ),

    "gi"

  );

  // Create an array to hold our data. Give the array

  // a default empty first row.

  var arrData = [[]];

  // Create an array to hold our individual pattern

  // matching groups.

  var arrMatches = null;

  // Keep looping over the regular expression matches

  // until we can no longer find a match.

  while (arrMatches = objPattern.exec( strData )){

    // Get the delimiter that was found.

    var strMatchedDelimiter = arrMatches[ 1 ];

    // Check to see if the given delimiter has a length

    // (is not the start of string) and if it matches

    // field delimiter. If id does not, then we know

    // that this delimiter is a row delimiter.

    if (

      strMatchedDelimiter.length &&

      (strMatchedDelimiter != strDelimiter)

    ){

      // Since we have reached a new row of data,

      // add an empty row to our data array.

      arrData.push( [] );

    }

    // Now that we have our delimiter out of the way,

    // let's check to see which kind of value we

    // captured (quoted or unquoted).

    if (arrMatches[ 2 ]){

      // We found a quoted value. When we capture

      // this value, unescape any double quotes.

      var strMatchedValue = arrMatches[ 2 ].replace(

        new RegExp( "\"\"", "g" ),

        "\""

      );

    } else {

      // We found a non-quoted value.

      var strMatchedValue = arrMatches[ 3 ];

    }

    // Now that we have our value string, let's add

    // it to the data array.

    arrData[ arrData.length - 1 ].push( strMatchedValue );

  }

  // Return the parsed data.

  return( arrData );

  var label = GmailApp.getUserLabelByName("South Loop Report");

  label.deleteLabel();

  // Move the first message in your inbox to trash

  var firstThread = GmailApp.getInboxThreads(0,1)[0];

  var firstMessage = firstThread.getMessages()[0];

  GmailApp.moveMessageToTrash(firstMessage);

}

Try replace your main function with

function importCSVFromGmail() {
  // gets first(latest) message with set label

  var threads = GmailApp.getUserLabelByName('South Loop Report').getThreads(
    0,
    1
  );

  threads.forEach(function(thread) {
    thread.getMessages().forEach(function(message) {
      // var message = threads[0].getMessages()[0];

      var attachment = message.getAttachments()[0];


      // Is the attachment a CSV file
      attachment.setContentTypeFromExtension();
      if (attachment.getContentType() === 'text/csv') {
        var ss = SpreadsheetApp.getActive();
        var sh = ss.getSheetByName('Sheet1');

        // parses content of csv to array

        var dataString = attachment.getDataAsString();
        var csvData = CSVToArray(dataString);


        // Remember to clear the content of the sheet before importing new data
        sh.clearContents().clearFormats();

        // pastes array to sheet

        var lastRowValue = sh.getLastRow();
        for (var i = 0; i < csvData.length; i++) {
          sh.getRange(i + lastRowValue + 1, 1, 1, csvData[i].length).setValues(
            new Array(csvData[i])
          );
        }
      }

      // marks the Gmail message as read and unstars it (Filter sets a star)
      message.markRead();
      message.unstar();
    });
  });
}

Best, Alex.

Quick note: you may also want to explore using Utilities.parseCsv() instead of CSVToArray, unless you need to support some unusual CSV format.
